An automatic nut internal thread quality tester is provided. The automatic nut internal thread quality tester includes a blanking module, a clamping module, a push rod module, a thread gauge driving module, and an axial pushing module. The blanking module is configured to control the nuts to be tested be blanked in series. The clamping module is configured to clamp the to-be-tested nut. The push rod module is configured to push the to-be-tested nut into the clamping module and restrict the blanking. A thread gauge of the thread gauge driving module is driven by a motor to detect the to-be-tested nut. When a torque measured by a torque sensor is greater than a threshold value, the motor reverses the thread gauge and the axial pushing module drives the clamping module away from the thread gauge.

An automatic nut tapping equipment is provided. The automatic nut tapping equipment includes a tap rotating mechanism, a nut clamping mechanism, an axial transmission mechanism, and a nut placing slot. The tap rotating mechanism includes a tap rotary motor and a tap, wherein the tap is driven by the tap rotary motor. The nut clamping mechanism includes a clamping assembly and a sliding rail, wherein the clamping assembly is disposed on the sliding rail and is configured for clamping a to-be-tapped nut to restrict the to-be-tapped nut from rotating. The axial transmission mechanism controls the clamping assembly to axially translate one pitch in response to the tap rotating one revolution, such that a forward nut-tapping motion and a backward nut-retracting motion are performed by the nut clamping mechanism. The nut placing slot is configured to arrange and control the dropping of another to-be-tapped nut.

A wind power excitation synchronous generation system having a maximum power determining unit and a control method thereof are disclosed. In this control method, dual input shafts and a single output shaft of a gear transmission mechanism are used, and two kinds of inputted power, such as wind power and servo motor control power, are integrated, so as to allow the output shaft to drive an excitation synchronous generator to generate electric power. In this system, a rotation speed and a phase of a servo motor are controlled, so as to allow the excitation synchronous generator to output the electric power with a frequency and a phase identical to the utility grid.
